Examines the advantages and limitations of visual aids in second language instruction. Visual aids can be used atmosphere, motivation, focus of attention, context, explanatory support, general comprehension, mnemonic support, cultural insights, and conversational stimuli. Their limitations include focusing attention away from the language,…

Findings of three tests given to 267 undergraduates (Wonderlic Personnel Test, Group Embedded Figures Test, and a case problem in 4 formats) were that neither graphic aids alone nor cognitive style alone significantly affected decision making; and when graphic aids and cognitive style are considered in conjunction, cognitive style is responsible…

Discusses the applicability of the machine-readable cataloging format for visual materials (MARC VM) to museum collections. A study is described that tested the utility of the VM format revision for museum objects, particularly as supported by OCLC, and recommendations are suggested for future enhancements.

Examines types of graphical representation as to their suitability for knowledge acquisition in primary grades. Uses the concept of mental models to clarify the relationship between external presentation and internal representation of knowledge. Finds that students who learned with highly elaborated and highly structured pictures displayed the…

Describes the learning experiences of young children meeting stem-and-leaf plots for the first time. Presents a vignette that offers a real and dynamic example of how young children can learn, use, and evaluate this powerful statistical display. (Author/ASK)

Examines how students interacted with a computer-based feature in Urinalysis Tutor(TM), "Compare and Contrast," which facilitated image comparisons. Three main image-viewing modes emerged. Overall, anchored viewing was the predominant image-viewing mode. Results suggest that a computer instructional program with a user-controlled…

Considers how visuals are constructions that are products of a writer's interpretation with its own "power-laden agenda." Reviews the current approach taken by composition scholars, surveys richer interdisciplinary work on visuals, and (by using visuals connected with the Human Genome Project) models an analysis of visuals as rhetoric.…

Presents a concept map that is a graphic referential tool, useful not only in the ordering of the reference material of a given domain, but also as a tool where the merging of verbal and graphic representation can have an advantage over the conventional linear structure of texts. (Author/VWL)

Discusses extand paradigms (ISBN, ISSN, ISMN, and the emerging ISAN). Models a procedure for assigning ISONs (International Standard Object Number) to objects and their surrogates. Describes resources requisite to the construction of the ISON, and outlines the necessarily cooperative work ahead if an ISON is to become a standard for visual…

This article describes the development of the video bookmark, hereinafter referred to as the videomark, and its application to the collaborative indexing of the lecture video in video-based distance education system. The combination of the videomark system with the bulletin board system (BBS), which is another network tool used for discussion, is…

This study examined the role of visual imagery in the centripetal execution principle (CEP), a graphic rule that is related to the drawing of complex figures that are composed of embedded geometric shapes. Sighted blindfolded children and children with early-onset low vision and early-onset blindness copied raised-line drawings (using only the…

The authors teach an astronomy unit in their seventh-grade course that they find never fails to motivate and stretch the imagination. The questions students ask are wonder-full: "What was here before the universe?" "If there was nothing before the Big Bang, where did energy and matter come from?" "Does the universe have a boundary, and if it does,…

Monica Adams, head librarian at Robinson Secondary in Fairfax country, Virginia, states that librarians should have the technical knowledge to support projects related to digital video editing. The process of digital video editing and the cables, storage issues and the computer system with software is described.

Some innovations in the images of cells and molecules that keep changing for new techniques and as a result of using new approaches to old methods are explored and new ways of illustrating cell and molecular structures are discussed. The three elements that play an important role in any biological image are aesthetic factors such as picture style…

A two-minute overhead demonstration using a molecular model kit is employed for illustrating the unique binding of cyclopropane. It is reported that most model kits, much like an sp (super 3) hybridized carbon atom, resist forming 60-degree bond angles.
